Title:
ANTENNA PERFORMANCE TESTER
Document Type and Number:
WIPO Patent Application WO/2020/060160
Kind Code:
A1
Abstract:
The present invention relates to an antenna performance tester comprising: a horizontal rotor (200) rotatable about a shaft part (110) to which a DUT holder (300) is detachably coupled; and a vertical rotor (500) to which a reference antenna holder (400) is detachably fixed and which is spaced apart from the side surface of the DUT holder (300), is installed perpendicular to the horizontal rotor (200), and is rotatable about a virtual center point lying at the center thereof. The present invention is advantageous in that: a reference antenna that is at a constant distance from a device under test can measure an RF while performing transmission and reception with the device under test in all directions, and can be extended or replaced depending on the frequency to be measured; and the influence of reflected waves on the RF measurement is minimized and thus antenna performance can be simply tested in an anechoic chamber or even in a semi-anechoic chamber.
